Due to their
high tensile strength to
density ratio, high corrosion resistance,fatigue resistance, high crack resistance, and ability to withstand moderately
high temperatures without creeping, titanium alloys are used in aircraft, armor
plating, naval ships, spacecraft, and missiles. For these applications titanium
alloyed with aluminium, vanadium,
and other elements is used for a variety of components including critical
structural parts, fire walls, landing
gear, exhaust ducts
(helicopters), and hydraulic systems. In fact, about two thirds of all titanium
metal produced is used in aircraft engines and frames. The SR-71 "Blackbird" was one of the first aircraft to make extensive use of titanium within its
structure, paving the way for its use in modern military and commercial
aircraft. An estimated 59 metric tons (130,000 pounds) are used in the Boeing 777, 45 in the Boeing 747, 18 in the Boeing 737, 32 in the Airbus A340, 18 in the Airbus A330, and 12 in the Airbus A320. The Airbus A380 may use 77 metric tons, including about 11
tons in the engines. In engine applications, titanium is used for
rotors, compressor blades, hydraulic system components, and nacelles. The titanium
6AL-4V alloy accounts for almost
50% of all alloys used in aircraft applications.
Due to its high corrosion
resistance to sea water, titanium is
used to make propeller shafts and rigging and in the heat
exchangers of desalination
plants; in heater-chillers for
salt water aquariums, fishing line
and leader, and for divers' knives. Titanium is used to manufacture the
housings and other components of ocean-deployed surveillance and monitoring
devices for scientific and military use. The former Soviet
Union developed techniques for
making submarines largely out of titanium.

Nice job using photos and videos!
